This fresh mix of zucchini, cherry tomatoes, basil leaves, olive oil and chopped walnuts makes an easy, no-cook side to simple grilled chicken or poached fish. Try it on its own for a light, detoxifying dinner.

If there's a break in the heat and you can fire up your oven, or if you have a toaster oven large enough to accommodate an 8-inch square baking dish, it's worth making this veggie version of the baked pasta classic, full of plenty of fiber, vitamin C, potassium, and no gluten.

Marjoram, with its hint of balsam, complements mild yellow and green summer squash in this simple crustless zucchini pie. It is topped by tomato slices and low-fat feta cheese, a lean choice. If yellow zucchini are unavailable, use all green zucchini.

These fresh, flavorful cocktail nibbles are high in protein and calcium -- and, unlike more traditional version of the classic, low in fat. Dijon mustard, capers, cucumber, and dill bring surprising taste and texture.

The next time the temperatures rise, don't reach for a sugary or chemical-laden soft drink. Instead, drop one of these ice cubes infused with cucumber and basil into a tall glass of water and keep your cool the natural way.
